KRG series includes radar level transmitters. Using 26GHz microwaves†, the liquid reflect them back to the instrument. The travel time, proportional to the distance between the surface and the gauge, is processed by instrument electronic generating output signal.
KRG instrument works in a non-contact and a non-mechanical way so:

• It has a least request of maintenance for long term;
• It can’t be damaged by the process liquid;
• It has a long durability;
